Anonymous users2024-01-24To achieve the degree of pollution, the outdoor exhaust pipe should have a large and certain exhaust volume and the concentration of "polluting gas in the pipe". What actually exists is a state of natural equilibrium, so the toilet sewage pipe leads to the roof of the building, which will pollute the air on the roof platform.

Anonymous users2024-01-23Generally, it does not pollute the ambient air on the roof. Mainly because of the small capacity of the odor emitted. The standard limits for organized emissions will not be reached.
It stands to reason that the smoke exhaust pipe should be installed vertically and discharged to the roof of the building to allow the smoke to diffuse, and the exhaust on the first floor may be blown into the room by the headwind.
It will affect the discharge, and it is still very affecting.
It's not the smell of return, it's the exhaust pipe, if the exhaust pipe seals the toilet manure pipe, it is a vacuum, if it is not breathable, the upper layer will spray out from the lower layer if the sewage is strong, if it is so, it will be very embarrassing.
1.If the material of the sewage pipe is PVC, it is best to buy an elbow like it and replace it. >>>More
No, this has the added benefit that the smell doesn't come up the tube. Sewage is top-down, it doesn't matter.
